Description
(1)WC基超硬合金の基材と、基材の表面に化学蒸着法によって形成された被膜とからなり、すくい面と、逃げ面と、すくい面と逃げ面との間に位置する切刃稜線部とを備え、被膜全体の総膜厚は平均膜厚で3〜20μmであり、切刃稜線部から300μm以内のすくい面に、クラックの進展角度が被膜の表面に対して45°以下の斜めクラックが1本以上存在することを特徴とする被覆切削工具。
(2)斜めクラックの進展深さが被膜の表面から0.3〜2μmである(1)に記載の被覆切削工具。
(3)被膜の表面におけるクラック間隔の平均値が20μm以上100μm以下である(1)または(2)の被覆切削工具。
(4)被膜の表面におけるクラック間隔の平均値が40μm以上60μm以下である(1)〜(3)のいずれかの被覆切削工具。
(5)被膜の少なくとも1層は、Tiの炭化物、窒化物、炭窒化物、炭酸化物および炭窒酸化物から成る群より選択された少なくとも1種からなるTi化合物膜である(1)〜(4)のいずれかの被覆切削工具。
(6)被膜の少なくとも1層は、酸化アルミニウム膜である(1)〜(5)のいずれかの被覆切削工具。
(7)被膜が、基材に接する内膜の少なくとも1層がTi化合物膜であり、内膜より表面側に形成される外膜の少なくとも1層がAl2O3膜であり、Ti化合物膜とAl2O3膜との間に、Ti化合物膜およびAl2O3膜と接して、Tiの炭酸化物、窒酸化物および炭窒酸化物、並びにTiとAlとを含む炭酸化物、窒酸化物および炭窒酸化物から成る群より選択された少なくとも1種の化合物からなる密着膜からなる(1)〜(6)のいずれかの被覆切削工具。
(8)斜めクラックが、1本以上、50本以下存在する(1)〜(7)のいずれかの被覆切削工具。
(9)斜めクラックが、3本以上、30本以下存在する(1)〜(8)のいずれかの被覆切削工具。
(10)クラックが、乾式ショットブラストまたはショットピーニングにより形成されたものである(1)〜(9)のいずれかの被覆切削工具。
(11)クラックが、投射材を被膜の表面に対して投射角度が30〜45°になるように投射することにより形成されたものである(1)〜(10)のいずれかの被覆切削工具。
(12)クラックが、投射材を50〜80m/secの投射速度で投射することにより形成されたものである(1)〜(11)のいずれかの被覆切削工具。
(13)投射材が、平均粒径100〜150μmで、ビッカース硬度が1000以上の材料からなる(11)または(12)の被覆切削工具。
(14)投射材が、Al2O3またはZrO2から成る(11)〜(13)のいずれかの被覆切削工具。
本発明の内膜は超硬合金基材の表面に化学蒸着法によって形成される。内膜の平均膜厚は、1.5μm未満であると被覆切削工具の耐摩耗性が低下し、15μmを超えると被膜の剥離を起点としたチッピングが発生しやすくなる。そのため本発明においては、内膜の平均膜厚を1.5〜15μmとすると好ましく、その中でも、内膜の平均膜厚を2〜13μmとすると、さらに好ましい。
本発明の外膜の平均膜厚は、1.1μm未満であると本発明の被覆切削工具のすくい面における耐クレーター摩耗性が向上せず、一方平均膜厚が10μmを超えると刃先が欠損しやすくなる。このことから、上部膜の平均膜厚を1.1〜10μmとすると好ましい。
本発明の密着膜の平均膜厚は、0.4μm未満であると本発明被覆切削工具の密着性が向上せず、また平均膜厚が2μmを超えると密着膜自体の強度が低下するため、密着膜の平均膜厚を0.4〜2μmとすると好ましい。
